lIMI'FROVIEID BED AND CUSHION-SPRING. I

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom it 'may concern:

Be it known that I, DANIEL E. SoMns, of Washington, in the county ofWashington, and District of Columbia, have invented anew and usefulSpling-Bed and Cushion; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, which make part of this specification, and inwhich- Figure 1 represents a perspective section `ot` a. bedstead,provided with my improved spring-bottom;

Figure 2, a view, in perspective, of a bedstead, showing another form ofthe same;

Figure Ska transverse section of a bedstead, in

which the outer tubes are of larger diameter than the others;

Figure 4, a perspective section of a modified form of spring;

Figure 5, a vertical section of a sofa; and

Figure 6, a similar section of a chair, to which my improvement isapplied -Figure 7, a horizontal section of a chair-bottom, showing adifferentV arrangement ofthe tubes;

Figure 8, an end view of a series of tubes, oi quadrangularcross-section;

. Figure 9, an end view, showing a device for uniting the tubes; and

Figure l1, a device for admitting and distributing air.

Figure 12 shows the position of the tubes when in serted one withinanother.

The object of my invention is to provide a simple and durablespring-bottom for beds, sofas, chairs, Sto., which can be cheaply andeasily constructed, and, when in use, b'e free from liability tobreakage or derangement; to which ends,

My improvement consists in one or more layers of tubes, of rubber prother elastic material, laid upon and within suitable framing, andcovered with a thin mattress or other covering, in the ordinary manner.

My Vinvention likewise comprehends the circulation of warm or coldwater, or air, through or between the tubes, for the purposeofmaintaining any desired degree of heat or cold in a bed, and therebyrendering it particularly adaptable to the requirement-s of a sickroomor hospital.

In the accompanying drawings, which show a convenient arrangement ofparts for carrying out the objects of my invention,

vA representsA the frame of a bedstead, and B B a series of elastictubes, laid upon it, arranged either longitudinally or transversely, orboth, and in one or more layers.

The tubes B may be of any desired diameter and thickness, and ofcircular, elliptical, or polygonal cross-section, as found mostsuitable.

In fig. 1, the tubes are shown as arranged transversely, and in iig. 3longitudinally, while in fig. 2, Y,

two layers are shown, one above the other, the upper being composed ofthe serpentine bends of a single tube.

In 3, the two outer tubes are of larger diameter than the others, forthe purpose of forming a species of' elasticI rail or guard, suitablefor use in a childs crib, or similar situations.

The tubes maybe `placed in the bed either separately, or in connectionwith each other, and may be eithervloose, or continedby cords, straps,`or other fastenings.

Fig. 9 shows the tubes provided with lateral langes be, which may beunited by riveting, bolting, or stitch- In ig. 8, they are shownofquadrangular cross-section, that form, or a circular or elliptical one,being optional.

For the purpose of specially adapting a bed to the requirements of ahospital or sick-room, by varying and regulating its temperature atpleasure, warm or cold water, or air may be passed through '0r betweenthe tubes, either with or without the use of an independent pipe.

In fig. 2, a separate water or air-pipe, C, is shown, passing throughthe upper serpentine tube, and provided with an elbow and stop-cock, towhichthe receiving and discharge-pipes` can be attached, both being atthe same end of the. bed.

In fig. 3, this pipe passes between thetubes instead of. through them,and, if deemed preferable, it may be dispensed with, and water or air`passed directly .through the tubes themselves.

By this means, it will be seen that a bed can be readily warmed orcooled at pleasure, and the comfort of a patient greatly enhanced.

My improvement is readily applicable to chairs, sofas, Sto., as shown infigs. 5 and 6, and to'portable or stationary cushions, pillows, &c.

In the chair-bottom represented in fig. 7, a different arrangement'ofthe tubes is shown, each being bent into quadrangular form, and unitedby having its diameter reduced at one end, which is then iuserted intothe other end.

A. similar arrangement may be made use of in a. bedstead, if desired.

In iig. 4, a compound spring is'showu, composed of a series of tubes, Bb b', one within the other, by which device a greater amount ofelasticity' can be made available than by the use of single tubes.

In. some instances, instead of conveying or circulating the air entirelythrough the tubes, a tube may be employed, which is closed at one end,and provided with numerous perforations or orifices, through.

the Whole or any desired portion of its length, into the open end ofwhich air is forced by an Vair-pump, bellows, or its equivalent, andescapes through the various perforations, so as to be dispersedthroughout the bed, for the purpose of cooling or Warming andVentilating the same.

Having thus fully described my invention,

Vhat I claim therein as new, and desire to secure by Letters Patent, is

1. A series of elastig tubes, one within another, springs for bed, sofa,and chair-bottoms and cushions, subst-antially as set forth.

2. A spring-bottom for beds, sofas, chairs, Ste., composed of a seriesof elastic tubes, arranged in one or more horizontal layers, and eitherlongitudinally or transversely, or both, substantially as set forth.

3. Circulating warm or cold water, or air, through.
